<jats:title>Background</jats:title>
<jats:p>The impact of air bubbles into the cerebral circulation after open heart surgery has been a topic of discussion since the introduction of the heart-lung machine. The aim of the study was to evaluate whether the use of a dedicated commercial sponge diffuser is better than a custom-made narrow section cannula or the absence of CO2 in preventing neurological events after aortic valve replacement via J mini-sternotomy.</jats:p>
</jats:sec><jats:sec>
<jats:title>Methods</jats:title>
<jats:p>Three cohorts of J-shaped mini-sternotomy performed at three different centers were prospectively compared: CO2 supplied via sponge diffuser, CO2 supplied via cannula, and no CO2 supply. Propensity matching was used to obtain comparable groups. The primary endpoints were postoperative stroke, transitory ischemic attack, convulsions, and dizziness. Secondary endpoints were 30-day mortality, duration of mechanical ventilation, and intensive care unit length of stay.</jats:p>

<jats:title>Results</jats:title>
<jats:p>275 patients were enrolled in the study. After propensity matching, the sponge diffuser cohort had a significantly lower duration of mechanical ventilation (<jats:italic>P</jats:italic> < 0.001) and 30-day mortality (<jats:italic>P</jats:italic> = 0.05) when compared to the cannula cohort and the no-CO2 cohort, a lower incidence of all neurological events (<jats:italic>P</jats:italic> = 0.03) and dizziness (<jats:italic>P</jats:italic> = 0.05) when compare to the no-CO2 cohort, and a lower intensive care unit length of stay when compared to the cannula cohort (<jats:italic>P</jats:italic> = 0.001).</jats:p>

<jats:title>Conclusions</jats:title>
<jats:p>The sponge diffuser used to deliver the CO2 into the surgical field during aortic valve replacement via J mini-sternotomy has been demonstrated to guarantee better neurological outcomes compared to a custom-made narrow section cannula or the absence of CO2.</jats:p>
